Bill Overview

Analyzed Economic Effects

4 provisions identified: 2 benefits, 2 costs, 0 mixed.

Child support after intoxicated driving deaths

Bentley and Mason's Law provides child maintenance when a qualifying intoxication-related driving offense causes a parent's death. A conviction, guilty plea, or no-contest plea triggers a required court order when the surviving parent or guardian petitions. Courts set payments using the child's needs, family resources, prior living standard, education, childcare costs, and child-support guidelines. Payments generally end at age 18, death, marriage, or active military service, with extensions for qualifying education or incapacity. Payments go to the surviving parent or guardian, or the state as guardian, and can be enforced through wage withholding.

Low-income drivers pay less for interlocks

Drivers with verified income at or below 150% of the federal poverty level pay 10% of the ignition interlock cost. This saves them 90% of the device cost. Income proof can include last year's federal tax return, income statements from the past three months, or a court order. Extra costs caused by not following the rules remain the driver's responsibility and are not discounted.

Interlock requirements expand for high-risk drivers

Missouri requires certified ignition interlocks for repeat intoxication-related driving offenses and qualifying offenses involving blood alcohol of at least 0.15%, property damage, or injury. License rules also cover specified suspended or revoked drivers with a prior alcohol-related enforcement contact. Covered drivers must show installation proof to regain a license or get limited driving rights, with devices on every vehicle they drive. Devices must stay installed for at least six months after license reinstatement. Violations in the final three months extend use until three straight violation-free months; failure to maintain required proof or devices can bring license loss and a class A misdemeanor.

Tougher penalties for harmful intoxicated driving

Criminally negligent intoxicated driving causing physical injury is a class D felony; serious physical injury makes it class C. Causing death through criminally negligent intoxicated driving is a class A felony. A later intoxicated-driving offense is also class A after a prior finding of guilt under the specified class B death-related provision. The specified class B fatal-driving offense requires at least five years in prison before parole or probation eligibility. Class A offenses under the intoxicated-driving law require at least ten years before eligibility.
